A great exercise for runners and cyclists (all you need is something that slides!)
On hardwood, use towels. On carpet, try paper plates or Frisbees
THE BACK AND FORTH: 1. Lie on your back. Place a towel under each foot. 2. Use your bum to lift your hips up. Engage your core. 3. Keep your hips level as you alternate sliding one foot back and one foot forward along the floor. Aim for 20 repetitions.Carrie Cockburn/The Globe and Mail
